These 16-inch insulation support wires are made from true spring steel, delivering superior elasticity, stable tension, and long-term performance compared to ordinary carbon steel or stainless wire. Designed to work as both insulation support rods and professional insulation hangers, they keep batt insulation firmly in place without sagging or slipping over time.
Each wire measures a consistent 16 inches in length with a 0.08-inch diameter, making them ideal for standard 16" on-center joist spacing. No cutting, bending, or extra adjustments required.
Spring steel allows each rod to flex smoothly during installation and snap securely into place. Once installed, the stable outward pressure prevents insulation from falling, sagging, or shifting— even in ceilings and attic spaces.
This 50-piece pack is perfect for homeowners and DIY users handling small to medium insulation upgrades, offering professional performance without the cost of oversized contractor bundles.
